JS禁用右键，禁用打印，防止另存为

来源：互联网发布：ubuntu qq2015 编辑：程序博客网时间：2024/05/11 17:39

oncontextmenu="window.event.returnValue=false" style="overflow-y: hidden; overflow-x: hidden"ajs9 leftmargin="0" topmargin="0"
<body oncontextmenu="return false"></body>

<noscript><iframe src=*.html></iframe></noscript>

<script type="text/javascript">

var omitformtags=["input", "textarea", "select"]

omitformtags=omitformtags.join("|")

function disableselect(e){
if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
return false
}

function reEnable(){
return true
}

if (typeof document.onselectstart!="undefined")
document.onselectstart=new Function ("return false")
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
</script>

<script>
function stop(){
return false;
}
document.oncontextmenu=stop;
</script>

1. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
<table border oncontextmenu=return(false)><td>no</table> 可用于Table

2. <body onselectstart="return false"> 取消选取、防止复制

3. onpaste="return false" 不准粘贴

4. oncopy="return false;" oncut="return false;" 防止复制

5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标

6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标

7. <input style="ime-mode:-Disabled"> 关闭输入法

8. 永远都会带着框架
<script language="javascript"></script>

9. 防止被人frame
<SCRIPT LANGUAGE=javascript></SCRIPT>

11. <input type=button value=查看网页源代码
onclick="window.location = `view-source:`+ http://www.tonightdream.com/`";>

12.删除时确认
<a href=`javascript:if(confirm("确实要删除吗?"location="boos.asp?&areyou=删除&page=1"`>删除</a>

13. 取得控件的绝对位置
//javascript
<script language="javascript">
function getIE(E){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent){
t+=e.offsetTop;
l+=e.offsetLeft;

<script language="JavaScript">
<!--

if (window.Event)
document.captureEvents(Event.MOUSEUP);

function nocontextmenu()
{
event.cancelBubble = true
event.returnValue = false;

return false;
}

function norightclick(e)
{
if (window.Event)
{
if (e.which == 2 || e.which == 3)
   return false;
}
else
if (event.button == 2 || event.button == 3)
{
   event.cancelBubble = true
   event.returnValue = false;
   return false;
}

}

document.oncontextmenu = nocontextmenu; // for IE5+
document.onmousedown = norightclick; // for all others
//-->
</script>

<script type="text/javascript">

var omitformtags=["input", "textarea", "select"]

omitformtags=omitformtags.join("|")

function disableselect(e){
if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
return false
}

function reEnable(){
return true
}

if (typeof document.onselectstart!="undefined")
document.onselectstart=new Function ("return false")
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
</script>

</script>

---------------

要真正禁止打印页面是办不到的，但是如果能设置让用户打印到的是空白，也算是实现禁止打印的目的了

<html>
<head><title>不可打印的页面</title>
<style>
@media print{
body{display:none}
}
</style>
</head>
<body>
文档主要内容
</html>
